outer bearing races

48 and 46, respectively, whereby the bearing assembly not only serves as a radial bearing but also serves as a thrust bearing to limit axial movement of the shaft 40 relative to the housing.

The shaft 40 includes a central portion 54, an intermediate portion 56 of relatively reduced diameter, and an outer end portion 58 of a diameter less than that of the intermediate portion, the inner bearing race 48 being pressfitted on the outer end portion and abutting the shoulder 60, between the intermediate and outer portions of the shafts 40.

A pair of drum-forming

disks

62 and 64, having an outwardly flared peripheral rim 66, each has a central opening 68 which is reinforced by an annular washer I8, which is spot-welded to the disk, the disks and washers being pressfitted onto the central portion 54 of the shafts 40, and non-rotatably keyed thereto as by the key I2.

A split, spirally formed band I4 is disposed between the

disks

62 and 64, which band is provided with a plurality of outwardly extending ears I6 which extend through the spirally positioned apertures I6 in the

disks

62 and 64, which ears are bent so as to abut the outer faces of the

disks

62 and 64, and thereby detachably retain the disks and the split ring members I4 in engagement with each other. As will be appreciated from a consideration of Figure 6, the ends of the split bands "I4 are offset from each other to permit the passage of the flexible hoses 80 therethrough, without necessitating a sharp bend in the hose.

In order to yieldingly bias the shafts 40 and the reel in a direction to wind the hose 80 thereon, there is provided a helical spring 82 which has the inner end thereof secured, as by a pin 84, to an annular hub member 86, which hub is non-rotatably attached to the intermediate portion 56 of the shafts 46, as by a key 88, the pin being disposed in a suitable recess 90 in the hub member. As is apparent from a consideration of Figures 2 and 3, the hub member 80 abuts the shoulder between the intermediate portion and the central portion of the shaft 40. The outer end of the helical spring 82 is secured, as by a pin 92 to one of the side walls, such as I4, of the housing. A spring shield plate 94 having a peripheral rim 96 and an outwardly extending flange 98 is detachably secured to the side walls I4 as by the nut I which is carried by the pin 92, a plurality of such pins preferably being provided, one of which serves as the anchor for the outer end of the helical spring 82. The shield plate 94 has a central opening I02 which abuts the packing ring I04 which is disposed above the central portion of the shafts 40, the shield plate also engaging the inner edge of the hub member 86, in a manner clearly apparent from a consideration of Figures 2 and 3.

A pair of centrifugally actuatable pawls I06 are pivotally attached to the disk 62 by means of stub shafts I68 which are secured to the disks, the pawls being selectively engageable with a notch H0 in the flanged sleeve H2 which is secured to the side walls I2 of the housing. It will be readily appreciated that whenever the

disks

62 and 64 are rotated at a relatively rapid rate, the pawls will be centrifugally actuated into a position out of engagement with the notch H0, but whenever the disks are rotated at a.relative1y lower rate, the pawls will be gravity-actuated into engagement with the notch.

The shaft 40 is provided with a pair of longitudinally extending passages I I4, each of which has an offset portion H6 extending radially of the shafts 40, an opening between the

disks

62 and 64, a pair of substantially L-shaped pipes H8 having one end thereof threadedly connected to the shafts 40, in communication with the passage H4, being disposed between the

disks

62 and 64, and communicative with the flexible hose 80, by means of a coupling I20. The outer ends of the shafts 40 are provided with an internally threaded counterbore I22 which counterbore threadedly receives one end I24 of an anti-friction bearing cup I26. An outer bearing race I28 is slidably fitted into the cup I26 and abuts a shoulder I30 which limits inward movement of the outer bearing race I28 relative to the cup, the inner bearing race I32 being slidably fitted on a sleeve I34 which is rotatably disposed within the bearing cup I26. The sleeve I34 has an outwardly flared end I36 which engages the inner end I38 of the bearing cup I 26, a hose elbow I40 being threadedly received on the outer end I42 of the sleeve I34, the hose coupling abutting the inner bearing race I32, in a manner clearly apparent from a consideration of Figure 3. As is conventional, suitable anti-friction bearing elements I44 are disposed between the inner and outer bearing races, in corresponding recesses I46, whereby the bearing assembly serves not only as a radial bearing but also as a thrust bearing so that tightening of the hose elbow I 40 on the sleeve I34 will urge the outwardly flared inner ends I36 of the sleeve into engagement with the inner end of the bearing cup I26. The elbow I40 has a convoluted extension I48 extending therefrom, for the reception of a suitable conduit I50 which is connected to the source of supply (not shown). An annular packing ring I52 is disposed about the sleeve I34 between the inner bearing race I32 and the offset externally threaded portion of the cup I 26, to further aid in preventing the escape of fluid through the coupling, the packing ring I52 further serving to yieldingly bias the flared end I36 of the sleeve I34 into seating engagement with the inner end I38 of the bearing cup I26, when the elbow I40 is tightened against the inner bearing race I32.

It is intended that the winding and reeling apparatus set forth is utilized to selectively wind and unwind a pair of hoses which are adapted to convey oxygen and acetylene to the welding and cutting torches, which are connected by couplings I54 to the hoses 80. It is accordingly intended that the spaces between the

disks

62 and 64 be such as to snugly accommodate a pair of the hoses 80, in sidewise alignment, as is best shown in Figure 2.

The housing of the winding and reeling apparatus is connected to a supporting structure by means of brackets I56, which are connected to the housing, as by fasteners I58, which brackets may be of any suitable construction, depending upon the type of supporting structure to which the housing is to be attached.

From the foregoing, it is thought that the operation and construction of the device will be readily understood, and further discussion is therefore believed to be unnecessary. However, since numerous modifications will readily occur to those skilled in the art after a consideration of the foregoing specification and accompanying drawings, it is not intended to limit the invention to that shown and described, but all suitable modifications may be resorted to falling within the scope of the appended claims.
